Final answer:
John Rawls's ethical decision-making is founded on his 'veil of ignorance' concept, key to his Theory of Justice, where decisions are made without knowledge of one's own social standing to ensure fairness.
Step-by-step explanation:
According to John Rawls, only a person ignorant of his own identity can make a truly ethical decision. This thought process is based on Rawls's concept of the 'veil of ignorance.'Rawls's 'veil of ignorance' is a fundamental element of his Theory of Justice, which suggests that ethical decisions should be made without any knowledge of one's place within the social structure.
By doing so, individuals would craft principles of justice that are fair and equitable because they would not want to risk being disadvantaged themselves. Consequently, the veil of ignorance allows for the creation of a just society by ensuring that no one knows in advance whether they would benefit or be impaired by a particular social arrangement, leading them to make choices that maximize liberty and minimize inequalities.
